By all accounts, Newt Gingrich is about to lose in Florida, and big. So looking back, how did Gingrich manage to pull off such a stunning victory in South Carolina?

In South Carolina, voters said Gingrich spoke to their conservative heart. Romney advisers say the 22-point switch in polls in the state took place after Gingrich's extended tussle with Juan Williams over racial sensitivity. "Williams was a stand-in for Barack Obama in people's minds," said one Romney adviser.

Uh-huh.
